Hydraulic DTH Drill Rig Equipped with Atlas Copco's Machine 21m Depth
We are a joint venture with Atlas Copco. For many years we have been insisting on quality first requirements to make products. The TDB7 inherits Atlas Copco's reliable technology and proven DTH drilling methods for reliable performance and high drilling quality.
The rig adopts a hydraulic direct control system, which is extremely simple to operate and maintain, and the number of components is effectively controlled, thereby greatly reducing the failure rate of the device and effectively improving the high reliability and maintenance convenience of the device.
Equipped with high-power and high-pressure Atlas Copco drilling machine, it has high efficiency in drilling hole. Our product--TDB7 is widely used in open mining and construction of earth work excavation, quarrying and slope processing and other drilling operations.
